Is there a DRY way to have a helper method for 2 different controllers?

For example:  
@user.create\_points\_account(10)  
@group.create\_points\_account(10)

and the helper method would look like this:

def create\_points\_account pts  
f = PointAccount.new(:points =\> pts)  
f.resource = self  
return false if !f.save  
end

Place it in a module somewhere and have both controllers to include that  
module.

I included it in the controller with helper :points and called it like  
above but I get an error:  
undefined method create\_points\_account

What could be the problem?

I changed it from helper :fund to include Fund and it’s included now but  
it doesn’t really help cause there’s still the error:  
undefined method `create\_fund’ for #User:0x5d52c6c

I guess I did not made myself clear.

I said create a module somewhere (usually under the lib folder), like:

#lib/points.rb

module Points

def create\_points\_account( pts )  
f = PointAccount.new(:points =\> pts)  
f.resource = self  
return false if !f.save  
end

end

And then at your controller:

class SomeController \< ActionController::Base

include Points

end
